The extent of the damage from a fire at TRG Imaging's Tutanekai St clinic has proved to be much worse than anticipated, with the rebuild time-frame likely to be the end of the year.
Service manager Debbie Cartwright said it was disheartening but made less stressful thanks to all the support staff had received.
The fire happened at the end of April and in May specialist fire investigator Bay of Plenty Coast Jon Rewi confirmed the cause was the failure of a fluorescent light fitting. It was thought then the rebuild would take six months.
Ms Cartwright said there was a lot more involved with the rebuild than first anticipated.
"The physical rebuild is likely to take longer and the end of the year is a more realistic time-frame to work towards. Until we get into the rebuild we don't know for sure."
